4) Back up and go to the System folder, then Apps.
5) Hit the big button on top to mount as Mount as R/O.
6) Press paste, it will ask you to overwrite file, press yes.
7) After this is done select the LiveWallpapers.apk and long press to bring up permissions. Change permissions to User- Read and Write, Group- Read, Others-Read then OK. Hit the big button on top to mount as R/W again!
